BELT-SHIFTING DEVICE.

Specification of Letters Patent.

Patented Oct. 10, 1905.

Application filed May 24. 1905. Serial No. 262,104.

1'0 (0/! who/rt it may concern:

Be it known that we, LEO SIEGWART, a citizen of Switzerland, and FRANK HILLNER, a subject of the German Emperor, residing at )Ilorgantown, in the county of Monongalia and State of \Vest Vir inia, have invented certain new and usefuf Improvements in Belt-Shifting Devices, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in belt-shifting devices, and has for its object to provide a novel form of belt-shifting device adapted to be manually operated.

A further object of this invention is to provide a device of the abovedescribed character which will be extremely simple in construction, strong and durable, comparatively inexpensive to manufacture, and highly efficient for manipulating a belt.

\Yith the above and other objects in view the invention finally consists in the novel construction, combination, and arrangement of parts, which will be hereinafter more fully described and then specifically pointed out in the claims, and referring to the drawings accompanying this application like numerals of reference designate corresponding parts throughout the several views, in which Figure 1 is a side elevation of our improved belt-shifting device partially broken away, illustrating the same in connection with a pulley. Fig. 2 is an edge view of the same, the lower end of the device being broken away.

of manipulating a belt to place it upon a pulley. Fig. 4: is a fragmentary side elevation of the upper end of the device. Fig. 5 is a similar view of the opposite side of the upper end of the device. Fig. 6 is an edge view of the same.

Our improved belt-shifting device consists of a rod or pole 1, upon the upper end of which is secured by a screw 2 or the like fas Fig. 3 is a side elevation of the upper end of the dev1ce,1llustratmg the operation rearwardly, as indicated at 7, and is preferably brazed or otherwise secured to the disk 4. The extreme end S of the arm 6 is pierced, and to this end of the arm is secured one end of a coiled spring 9, while the other end of said spring is secured, as indicated at 10, to the rod or pole 1. The arm 6 issubstantially semicircular in contour and is provided upon its upper end with a T connection 11, in which is secured by a set-screw 12 a rod or a piece of pipe 14.

The manner of manipulating our improved belt-shifter is as follows: In the accompanying drawings we have illustrated a pulley 26 mounted upon a shaft 27 and a belt 28 passing over said pulley. In Fig. 3 of the drawings we have illustrated the belt as being carried by the shaft 27, and should it be desired to place the belt upon the pulley 26 our improved device is manipulated to place the rod or section of pipe 14 in engagement with the belt 28 directly under the pulley 27. The revoluble motion of thepulley will carry the rod 1d around the wheel as it revolves until the position is reached illustrated in Fig. l. of the drawings, at which time the rod 14: will be released from the wheel and the device may be removed from the pulley. This operation causes the belt to engage the pulley 26, and the traveling of the rod .14 around the pulley is permitted by the curved arm 6, which surrounds the shaft 27, as clearly illus trated in Fig. 1 of the drawings. Should the rod 1 be held at a greater angle to the shaft 27 than that illustrated in Fig. 1 of the drawings, the curved arm 6 may be moved to such an extent as to carry it out of its normal position, and upon the release of the rod 1% by the pulley and belt the spring 9 will return the curved arm to its normal position.

It is evident from the foregoing descrip tion, taken in connection with the drawings, that we have devised a novel device which can be readily manipulated by an operator to replace a belt upon a pulley or belt-wheel, consequently dispensing with the dangerous practice of artisans in placing belts upon the pulleys by hand.

Our improved device may be made of any desired length, whereby it can be used in connection with pulleys and shafts that are suspended from the ceilings or framework of shops, or the device may be constructed with a short handle and used in connection With the pulley or belt Wheels of machinery.

What We claim, and desire to secure by Letters Patent, is

1. In a device of the type described, the Combination With a pole, of a curved arm pivotally attached'to said pole, said curved arm having a rearWardly-projecting end, a spring attached to said rearwardly-projecting end and to said pole and a laterallyprojecting rod carried by the free end of said curved arm.

2. In a device of the character described, the combination with a pole, having a disk curved arm, and a spring attached to said 20 curved arm and attached at its opposite end to said pole.

In testimony whereof We affix our signatures in the presence of two Witnesses.
